A few hours ago I wiped and had a pinkish discharge and I thought it odd I'd be starting 5 days early but put a tampon in anyway. When I went to change there was just a little brown on it (sorry tmi) and nothing else. Not really cramping like I do on my period. Could this be implantation bleeding?? Its been about 11 days since we did the deed and I'm pretty positive I ovulated that next day according to my cervical mucus.
